Builders in Findon

Extensions, renovations and careful work on flint and period cottages in the village. Family-run, third generation, and only minutes up the road from us.

Our doorstep

A village we know well

Findon sits just north of Worthing, under the Downs. We are there often.

Findon is a mix. Flint and brick cottages around the village and the Square, older houses that have been added to over the years, and larger detached homes on the edges with room to extend. The two ends of that mix need different handling. A cottage needs patience and the right materials. A big detached house is usually about layout, light and getting the ground floor working properly.

We are based at 51 Northbrook Road in Worthing, so Findon is a short run for us. That matters more than it sounds. Our team gets there early, the same faces turn up each morning, and if something needs a decision we are on site rather than three counties away.

The company is family-run and third generation with 65 years in the trade behind it, and over 30 years of combined experience on the tools. We carry out the whole job with one team, including carpentry and joinery, electrics, plumbing and heating, groundwork, rendering, flooring and roofing, so you are not project managing five separate firms.

Findon at a glance

Findon sits just north of Worthing under the Downs, and we are there often. A cottage needs patience and the right materials; a big detached house is usually about layout.

We are based at 51 Northbrook Road in Worthing and we cover Findon as part of our normal patch, not as a special trip. That is the practical difference: the same faces each morning, materials when we say, and Joe able to stand in the room with you if a decision needs making.

Extensions on downland homes and cottage work

Extensions on downland homes

Most of the extension work around Findon is at the back: opening the kitchen up to the garden, adding a family room, or squaring off an awkward original layout. On the larger detached houses there is often room for a side return or a double-storey addition as well.

What we look at before pricing an extension here:

  • Ground conditions and existing foundations, which vary on chalk and sloping plots
  • Drainage runs and where the new soil and surface water will go
  • How the new roof meets the old one, and whether the ridge heights work
  • Which walls are load bearing and what steels the opening will need
  • Whether the design needs planning permission or falls under permitted development

See our extensions page for how we run the build, or structural alterations if you mainly want to take walls out and rework the ground floor.

Flint, brick and older cottages

Older village property is rewarding to work on and unforgiving if it is rushed. Flint and soft brick do not behave like modern blockwork. Solid walls need to breathe. Roof timbers that have been there a century have usually moved, and a new opening has to be propped and supported properly before anything comes out.

Our approach on cottage work is straightforward. We survey what is really there, agree the materials with you before we order them, and match brick, flint and mortar to the existing building as closely as we can. Where the fabric is damp or poorly ventilated we deal with the cause rather than covering it up.

If the property is listed or sits in a conservation area, consent is needed before the work starts and the details have to follow what has been approved. We build to that and work with the local-authority inspector as the job goes on.

FAQs

Common questions

Do you cover Findon village and the lanes around it?

Yes. We are based in Worthing, a few minutes down the road, and cover Findon, Findon Valley and the surrounding downland properties. Access and parking are worth discussing at the survey so we can plan deliveries sensibly.

Can you match flint and old brickwork?

We work with what is already on the building rather than the nearest modern equivalent. Brick, flint and mortar are chosen to suit the existing wall and agreed with you before we order anything.

How long will my extension take?

We will not put a number on that before seeing the job, because ground conditions, design and approvals all change it. You get a written programme with your quote so you know the sequence and roughly when each stage happens.

Do I need to bring in other trades?

No. We self-deliver carpentry and joinery, electrical work, plumbing and heating, groundwork, rendering, flooring and roofing, so one team handles the job from start to finish and one person is accountable for it.

Is the quote free?

Yes. Quotes are free and no obligation. Call 01903 411992 or 07949 172906, message us on WhatsApp, or email rockshore_building@outlook.com and we will arrange a visit.
